I've got remote databases on hosting. Can Flash Builder generate Spark Form with similar structure from database table?
Your Flex application will call a backend script that will access your table definition. Depending on your database, statements will differ.
Here is an example using MySQL: "SHOW COLUMNS FROM MyTable"
Your application will then iterate on the results and generate fields according to your logic.
Basically yes. 1st of all you need to connect to the service which u are providing from your backend, and then check the follow article :

We are doing some CRUD operation in DEV environment and data is saved in database. For other environments(like Staging/Prod) we want to copy those records from DEV database and paste to Staging/Prod when required using asp.net MVC. Is it possible? Could you please suggest some pathway in order to accomplish this?
You can accomplish this using a linked server:
https://learn.microsoft.com/en-us/sql/relational-databases/linked-servers/create-linked-servers-sql-server-database-engine?view=sql-server-ver15
This involves creating a link between one database server and another (they must be able to see each other on the network). You can then reference the linked server like this:
INSERT INTO [LinkedServerName].[Database].[dbo].[Table] (......
Alternatively you could use a paid for tool like SSMS tools which can generate insert statements on a per table basis: https://www.ssmstoolspack.com/
I am creating web service in zend framework which uses DynamoDB. So I installed DynamoDB in local. But it's not easy to use. Even for inserting data and update any data for testing for purpose I have to write a script.
Is there any DynamoDB client available for MAC ? In which we can insert/update/delete data from UI.
EDIT
Doubts
1) Do I have to run a SQL to see table data? I thought there would be GUI for this.
2) I am not able to use where clause in SQL. What if I want to see one or two records from all? Is there a way to use conditions in this?
3) All fields of a row is not visible and I am not able to scroll it horizontally ?
YES! I've finally found a solution after struggling with this myself:
Run your local dynamodb jar with the following command java -jar DynamoDBLocal.jar -dbPath . [this will create a file in whatever directory the Dynamo jar is located in].
Download SQLite Database Browser and extract/install it.
Start SQLite Database Browser
Navigate to "Open Database" from the file menu
Navigate to the directory from 1. Select the file [in this case, ****_us-east-1]
You should then see the database contents!!
Hope this helps - it's been frustrating me no end!

Yes - you can do a simple "select" statement, for instance in my examples: "SELECT * FROM tweet_item" returns me the following screenshot:
Seemingly inadvertanyl - whilst I couldn't get the direct SELECT * FROM XX WHERE XX to work, the like statement does. For instance SELECT * FROM tweet_item where tweet_item.hashKey like "%425665354447462400%" returns me the tweet with tweet_id [my hashKey] of 425665354447462400:
Strange - I seem to be able to scroll quite happily [although it is Windows not Mac]. It also automatically tries to re-size the outer frame, too.
I ran into this problem and found a relatively new solution : https://github.com/aaronshaf/dynamodb-admin
It has provision for GET/POST/PUT/DELETE.
Although its a paid product, which is a bummer, RazorSQL now supports DynamoDB as well, and does let you change the AWS endpoint to point to a local installation.
The mac version (with a free trial) is available here:
http://razorsql.com/download_mac.html
Here is a very useful ui tool https://github.com/YoyaTeam/dynamodb-manager，It supports almost all data operations。
For Eclipse users:
Amazon provides AWS Toolkit for Eclipse IDE. It can view local and cloud databases. Also if you are using different regions, it has ability to choose from different regions.
You can create attributes, add keys etc..
For installation follow this link: http://docs.aws.amazon.com/toolkit-for-eclipse/v1/user-guide/getting-started.html
Dynobase is new DynamoDB GUI Client which also lets you browse and manipulate local DynamoDB instances: https://dynobase.dev/dynamodb-local-admin-gui/
Unfortunately, it's paid but there's free 7-days trial, works on Mac, Windows and Linux: https://dynobase.dev/
I'm working with sqlite and qt. I understand that sqlite doesn't have native user access control and am fine with that, and have a plan for controlling access using my application - set up some user groups in a db and authenticate on the app side.
What I would like to know is if there is an easy way to stop my views on QSqlRelationalTableModel data from updating the database (i.e make the database readonly).
I am currently using an editstrategy of OnFieldChange, if I change it to OnManualSubmit for example (without implementing a submit call), will that prevent updates to the dB?
Is there a cleverer way of doing this? Like making the view readonly?
If you create views, then they will be read-only since sqlite doesn't support updating views:
http://www.sqlite.org/lang_createview.html
EDIT
Following-up on your comment, is the QSQLITE_OPEN_READONLY connection setting what you are looking for?

What do i need to do in order to be able to query across multiple databases which are in the same db engine?
I have added the .edmx file of 1 database, but i only need 1 view from another db.
Thanks in advance!
Here are a couple of options:
Depending on your database platform, make the view from your second database available in your first database. If you're using SQL Server, you can use a linked server. If you're using Oracle, you can use a DB Link. Simply create a view in your main database where the view's select statement utilizes the linked server or db link to reference the view from your second db.
Create a second .edmx file for your second database. This is the route I chose recently. However I was dealing with one SQL Server DB and one was Oracle DB. There were also multiple tables and functions from both being used. I determined that it was cleaner in my case to create two separate data access projects, one for each DB, each with it's own .edmx.
Hope this helps.
I would like to find a way to create and populate a database during asp.net setup.
So, what I'm willing to do is:
Create the database during the setup
Populate the database with some initial data (country codes or something like that)
Create the appropriate connection string in the configuration file
I'm using .NET 3.5 and Visual Studio 2005, and the Database is SQL Server 2005.
Thanks in advance.
If you are creating an installer I'm sure there is a way to do it in there, but I am not all that familiar with that.
Otherwise, what you might do is the following.
Add a application_start handler in the Global.asax, check for valid connection string, if it doesn't exist, continue to step two.
Login to the server using a default connection string
Execute the needed scripts to create the database and objects needed.
Update the web.config with the connection information
The key here is determining what the "default" connection string is. Possibly a second configuration value.
Generally, you'll need to have SQL scripts to do this. I tend to do this anyway, as it makes maintaining and versioning the database much easier in the long run.
The core idea is, upon running the setup program, you'll have a custom action to execute this script. The user executing your setup will need permissions to:
Create a database
Create tables and other database-level objects in the newly-created database
Populate data
Your scripts will take care of all of that, though. You'll have a CREATE DATABASE command, the appropriate CREATE SCHEMA, CREATE TABLE, CREATE VIEW, etc. commands, and then after the schema is built, the appropriate INSERT statements to populate the data.
I normally break this into multiple scripts, but YMMV:
Create schema script
"Common scripts" (one for the equivalent of aspnet_regsql for web projects, one with the creation of the Enterprise Library logging tables and procs)
Create stored procedure script, if necessary (to be executed after the schema's created)
Populate initial data script
For future maintenance, I create upgrade scripts where a single script typically handles the entire upgrade process.
When writing the scripts, be sure to use the appropriate safety checks (IF EXISTS, etc) before creating objects. And I tend to make mine transactional, as well.
Good luck!
Well, actually I found a tutorial on MSDN: Walkthrough: Using a Custom Action to Create a Database at Installation
I'll use that and see how it goes, thanks for your help guys, I'll let you know how it goes.
If you can use Linq to Sql then this is easy.
Just import your entire database into the Linq to Sql designer. This will create objects that describe all objects in your database, including the System.Data.Linq.DataContext derived class that encapsulate the entire database setup.
Now you can call DataContext.CreateDatabase() to create the database.
See here more information.
